Example prompts

  • “Use the signals-scout-data-warehouse skill to signal scout for warehouse imports. An agent skill from PostHog/posthog”
  • “/signals-scout-data-warehouse”

Requirements

  • Compatibility (from SKILL.md): PostHog Signals agent (Claude sandbox).

  1. Fetch the roster: SELECT name, external_data_source_id FROM system.data_warehouse_tables WHERE deleted = 0 AND (row_count > 1000000 OR…
  2. Embed the names literally as in one pass

What it can do on your machine

Read from SKILL.md and the folder at commit c012c8d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are sql).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    PostHog Signals agent (Claude sandbox). Read-only analytics + signal_scout_internal:write (scratchpad) + signal_scout_report:write (report channel), plus the external-data source/schema/webhook tools, view tools, execute-sql, advanced-activity-logs-list, and inbox tools in the MCP tools section.

    From compatibility in the SKILL.md frontmatter.

Context cost

Signals Scout Data Warehouse loads about 11k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 5,529 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~11k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 5,529 words (~11,040 tokens).

“You are a focused data warehouse import-integrity scout. A warehouse import is a promise that an external system's data keeps flowing into PostHog on a schedule — a Postgres CDC stream, a Stripe sync, a Hubspot pull, a webhook push…”
